500ps is one cycle at 2GHz. A cache miss is much longer. Any timing
involving software is unlikely to be that accurate.
Gigabit ethernet (1000BASE-T) runs at 125MHz - 8ns. So even if you have
hardware level timing, you wi
Hi
I suspect that somebody somewhere in the documentation
process got accuracy and resolution a bit crossed up.
Resolution would be pretty easy to observe.
In a broad sense, to be accurate to 1/2 ns, the time base in
the card would need to be pretty good. Even with a good
onboard reference,

Hello,
I have a board that is a NTP server. Any ideas on how to test its accuracy?
To check it roughly I sync my PC to it, maybe set the time to +3 hours and
confirm my PC follows.
